VETERINARX APPLIANCE FOR FACILITATING THE PARTURITION OF COWS IN CALF New. 1, 1932.

Fild March so, 1951 Patented Nov. 1, 1932 UNITED STATES] ULRIC RANSY, OF STAVELOT, BELGIUM VETERINARY APPLIANCE FOR FACILITATING THE PABTUIRITION OF COWS IN CALIF Application filed March 30, 1931, Serial No. 526,467, and in Belgium April 4, 1930.

The present invention has for its object a veterinary apparatus useful for drawing the calf from the body of the cow,'in case whenv the delivery is particularly laborious.

The machine in conformity with the invention comprises three distinctive parts, namely the head portion, which takes rest on the animal, the body or frame of the machine, and a traction mechanism. These three portions are connected in such a manner that the apparatus can be adapted for any position of the cow and will secure, therefore, a fixed position of the resting portions upon the animal when the apparatus is working.

The machine in conformity with the in vention will be described hereafter with reference to the accompanying drawing illustrating a preferred form of embodiment.

Fig. l is a side elevation;

Fig. 2 is a plan view of the machine;

Fig. 8 is a section on line 33 of Fig. 1;

Fig. 4 is a section on line %l4 of Fig. 1;

Fig. 5 is a plan view of a modified form of embodiment of the traction mechanism.

The head 6 of the machine is made from a flat shaped iron in a very particular form, sodetermined that the machine will find a perfect support on the hind quarters of the cow, thus completely clearing the passage and only exerting pressure on such parts of the body capable of supporting it, without harm to the constitution of the animal and to the good prosecution of the delivery.

The arms h, Fig. 3, of the lower portion of 1 the head rest on the buttocks of the cow clearing the passage. The branches 2' of the up per portion of the head, Fig. 2, bear on both sides of the sacrum. This particular form of the head will secure a fixed rest of the machine in front of the passage during the plete movable circle. The tail of the animal can be easily lifted, and in order to avoid injuries to the animal, cushions e are fixed to the branches h and 2'.

The head portion of the machine is connected to the frame by means of two rod irons y engaging the tubes is forming the body or frame of the machine. The knuckle at the other end of the rods 3 is engaged in an element 7' forming shell. Those two shellshaped elements are fixed on the depending branches h of the head portion 6. In this construction, the head 6 can swing with respect to the plane formed by the tubes is.

The frame of the machine is constituted with two steel tubes is connected to each other, on the one hand by means of a flat iron Z, and fixed, on the other hand, to a flat iron hoop m (Fig. 4:) this hoop is retained in a frame a formed with U-irons. This frame costitutes the support for the complete machine and ends with two wheels or castors 0 allowing an easy manipulation and placement of the machine.

The hoop m rotates freely about its center in the frame a.

This particular connection of the body of the machine with its support will allow said machine to be rotated about its main longitudinal axis. Consequently, whatever be the position of the hind quarters of the cow lying down, it will be always possible to bring the machine exactly in that place which it wants to occupy, although the support remains lVithin the tubes k are lodged springs is, upon which abut the rod irons y supporting the head portion of the machine. The springs are intended to absorb the shocks and eventually to compensate the pressures in the case when the head will exert a more considerable pressure on one side than on the other. In this case, one of the springs will be further compressed. Slots 3) are provided in the tubes 70, to act as guide-ways for the rod irons supporting the head portion; these rods are each provided with a pin 9 engaging in the corresponding slot 10.

The traction mechanism is formed with a drum r, upon which the traction cable a is engaged. The rotary movement is imparted to the drum by means of one of the levers t, which are provided with a ratchet 14 adapted for driving a ratchet wheel 1;. The drum 2 is furthermore provided with two ratchet wheels with catches w. The traction mechchili; 6f the animal.

f tion mechanism. By this structure, the machine becon'ies extensible.

When the cow is lying down, the machine is brought in position so that the head ortion e is adapted on the hind quarters 0 the chine being more 'or less in line with the The'end of the cable wound on, the drum of the traction mechanism is fixed to the string joining the hoofs' of the calf, which at this moment protrude i from the bod of the mother. From this moment, on eac expulsive effort made by the cow, a certain traction will be operated on the cable by rotating the drum 1" upon which 201 cable is d, After a number of op erations of this kind, the calf will be finally drawn out of the bodylof the mother.

The advantageous character of the traction, mechanism as described resides in the fact that, whatever the position of the machine may be, it remains very easy to act on one of the levers .t which is best at hand. Moreover, said mechanism allows the tractions on the calf to be exactly synchronized with the expulsive efforts of the mothcr, and to, closely survey all the movements of the latter. I

In the modificationof ,Fig. 5, the traction mechanism is substantially doubled; it is ada ted to allow a separate. traction on each of e members of the calf. In laborious deliveries, where the calf is wery big, itis useiul to draw on one member to make it proess separatel and then to operate on the 0 e11, while ho ding the former in place.

A central shaft (1 connects the two rod i1, Inflthe middle portion of this centra shaft retates a single lever t provided with two ratchets u, each acting on a ratchet wheel 12. As in the model described herebefore, each of the two small drums 1' is furthermore provided with a second ratchet with catch. The two. ratchets fixed to the lever t being movable, it is possible to make the lever act at will on the left hand drum only or on the right hand drum, only, or. on both drums together.

I claim:

1 A veterinary appliance for facilitating the, parturition of cows, comprising in combination; a shaped head, portion made of flat irons, having a substantially horizontal part torest on the hind quarters and co. asub$tantially depending part engaging the buttocks and clearing the passage, cushionirfi devices on said headportion, a longitudin framework comprising two parallel and interconnected tubes, knuckle-joint connecej; tiens between the head portion and the tube animal, the main longitudinal axis of the ma-.

ends, a movable support for said framework, and a traction mechanism at the end of the framework opposite to the head portion.

2. A veterinary appliance for facilitating the (parturition of cows, comprising a shaped hea portion engaging the hind quarters of the animal, two parallel and interconnected tubes forming a frame, knuckle-joint connected rod ends adapted to the head portion and engaging the frame tubes, cushioning a;
